MAcHINn'roR ?RINTING TICKETS.

" application filed January To (twin/ 10212 it 22mg concemi Be it known that I, THOMAS K. Swain-x1- son, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Printing Tickets, of which the following is a specification.

l his invention relates to machines for printing tickets,and it has particular relation to an improved mechanism for imprinting the lot numbers or other identifying data successively upon clothing tickets which are to be attached to garments, or upon other or analogous tickets which are fed through the machine in continuous strips comprising successively the respective ticketunits. V

The object of my invention is to provide a simple and improved mechanism ofthe character set forth, whichwill possess advantages in point of convenienceand delicacy of adjustment, positive and effective act-ion, economy in construction and general eth- 5 ciency.

lhe'present invention relates especially to certain ii'i'iprovements upon the type of machine shown in the Keller Patent'llo. 1,485,-

270, of February 26,1924, whereby control of the conditions of delicate adjustment is more conveniently effected'and maintained, andwhereby a more perfect adjustment for the printing impression is secured.

Referring to the drawings,"16 designates a suitable uprigl'it frame which supports in 1 media asshown in the previous Keller pat--- the inking-roller The printing media may,

cut before mentioned comprising type-discs,

20, formed by a metallic plate and having a circular periphery which at equi-distant points thereon is provided'with projective type-heads, 21, having the characters to be print-ed. assembled together successively and sideby side in fixed position upon the main shaft, to be carried thereby in its revolution, constitute a printing drum having at each. cross series of type-heads the desired series of characters reprcsenting'the f lot numbers 7 or other identifying data to be printed. A platen or bed of a-ny suitable construction, as indicated at 22, is mounted in relative po siti'on beneath the printing drum, and they continuous ticket-strip, shown at23, is fed Said typediscs when collectively in and through the mechanism between the type-heads 21. and said platen or bed. The latter has a curved periphery and is usually of drum form and revolubly mounted, and the respective cross-series of type-heads 21 of the revolving printing drum contact with and imprint upon the respective spaced units of the continuous ticket-strip 23 at the apex of the successive arcs of the curved periphery of the platen in the revolution thereof, the drum-platen being driven in its movement relative to the printing drum by a gear, shown at 24;, suitably comprised in the driving mechanism of the machine and meshing with the gear 19 of the printing media driving-shaft 17 to impart motion to the latter.

The foregoing mechanism, as above described, I have herein shown as substantially the same as that in the before-mentioned Keller patent, though it will be understood that the general machine mechanism and character of printing media may be of any suitable or desired construction adaptable to the conditions of the improved mechanism constituting the present invention and improven'ients and as hereinafter described.

In machines of the class to which my improvements especially relate, an inking drum or roller, as at 25, is provided and mounted to contact with the type heads 21 of the printing media to supply the ink thereto. Said inking drum is suitably mounted above the printing drum and usually carries a felt ink-pad at its cylindrical surface.

In the operative conditions and service of ticket-printing mechanisms of the class to which my invention is especially directed, it is an important desideratum that a very delicate adjustment of the plane of the typeheads of the printing media be permitted, to compensate for very slight variation in the thickness of the paper ticket-strips which are fed through the mechanism between the printing-heads 21 and the underlying platen or bed, or for wear of the printing characters. In such adjustment the plane of the type-heads is varied by adjustment of the plane of the main carrying-shaft, 17, whereby the peripheral printing characters of the printing media are brought to a position of adjustment towards or from the periphcry of the platen or bed 22.

In the before-mentioned Keller patent, an adj ustmcnt mechanism for the purpose j ust stated comprises a bushing member having a cylindrical circumference turnably mounted in a corresponding cylindrical. opening in the framework, 16, and having a longitudinal cylindrical bore on a plane eccentric to the center or axis of the bushing in its turnable adjustable movement, through which bore the revoluble main printing-media shaft passes and has its bearing. Thus, 'a slight turning movement of the eccentric-bore bearing-bushing would effecta very delicate variation in the plane of the printing-media shaft. In such previous construction, said turnable bushing is locked in adjusted position by a circumfer ential flange at its inner end, adapted to bear againstthe inner face of the framework, and an externally-threaded opposite or outer end carrying a lock-nut adapted to seat against the opposite or outer face of the framework.

My present invention is designed to provide improvements not only in the character of an adjustable bearing-bushing for the purpose above stated, but also in the con struction for setting and locking or maintaining such bushing in adjusted position, and in the eccentric character of the bushing as a bearing for the printing-media shaft, whereby the conditions of extreme delicacy and convenience in the adjustn'ient action and positive maintenance of the adjusted position will be enhanced and a perfect relationship of the plane of the printing-heads to the surface of the platen will be preserved in the adjustable variation of the plane of the carying shaft, substantially as hereinafter set forth.

In carrying out the improvements just indicated, the bearing-bushing member has a body portion, 26, which is preferably of disc shape having a fiat or plane inner face, 27, and a circular periphery. Said body has a tubular cylindrical extension, 28, projective from its inner face and seated in a cor responding cylindrical seat, 29, in the frame 16, whereby said bushing member is turnably movable in said seat. The bushing member has a longitudinal bore, 30, extending through the body-disc 26 and the cylindrical extension 28 and constituting the bearing for the re-voluble printing-media shaft 17, and the cylindrical circumference of said extension 28 is eccentric to the center of said bearing-bore. The bore 30 is in its longitudinal extent preferably in the plane of the center of the bushing body-disc 26 and is eccentric to the cylindrical circumference of the body-extension 28 which is turnably seated in its mounting, said extension being itself eccentric to the center of said body-disc. Thus, when the bushing member is turnably adjusted in its cylindrical seat the plane of the printing media shaft, and the peripheral printing characters of the printing drum carried thereby, will be varied with relation to the periphery of the impression platen or bed, and afford the desired adjustment for the printing impression as before described.

A tubular extension, as at 31, is also preferably provided projectively from the outer face of the bushing body-disc 26, in line with the center thereof, through which crably has the bore is extended, to form an extensionbearing for the main printing-inertia shaft 17. p The bushing member is l'ockedin its desired adjusted position and clamped in its seat-mounting with its inner face against the frame-work, by means'of set-screws, 3232, passing through segmental slots, 33-33, in the bushing-body-disc 26 at opposite sides of the center thereof, and entering the "frame 16. The printing-media shaft- 17 is secured. in its revoluble mountingin the bore 30 of the eccentric bushing by means of a collar, 34;, carried by the shaft at its outer end and bearingagainst the end of the outer extension 31 of the bushing, said collar co-acting with the fixed gear-hub 18 whi h bears against the end of the inner extension 28 of the bushing member, and being positioned by means of a set-screw, 35.

A very delicate and convenient adjustment of the eccentric bearing-bushing is effected by means ofadjusting-screws, 36 36, extending downwardly. through the framework and respectively bearing against shoulders, 3737, formed by recesses, as at 538 353, in the inne' face of the lnishing body-disc 26, said adjusting-screws and shoulders being respectively at opposite sides of the center or axis of the body disc of the turnable bushing and the degree of adjustment being limited by the end walls of the respective recesses 38. 'Thus, by" releasing the set-screws 32 and respectively operating the adjusting-screws 36 at opposite sides of the bushing member, the desired delicate degree of adjustment of the latter in its eccentric turna-ble mounting will be effected, after which the set-screws are again operated to secure and clamp the lnishing in its adjusted position. The adjustment action is therefore positively and :mcurately effected by mechanical screw-action, and not by Imanual turning of the bushing as is the case with the mechanism of the befmementioued Keller patent, and any indefinite condition of adjustment by manual. turning of the bushing is thus effectively precluded.

In'the preferred mechanism related to the mounting of the adjusting-screws 36, a supplementary frame-block, 39, is mounted upon the main frame 16 by means of a shoulder-rest, i0, and securing-screws, -it1l:1, extending through the body of said framebloclr beneath said shoulder-rest and at opposite sides and entering the frame 16, the adjnetting-screws 36 for the turnable bushing being threaded downwardly through the body of said frameblock. The latter is mounted directly above the circular bodydisc 26 of the turnable bushing, and prefits under side segmentally curved, as at 42, in an arc corresponding to the circular periphery of the bushing- 'l.=ody-disc, and preferably said frame-block forms the mounting for the shaft of the inking drum, by means of a top extension, 43, havin a cylindrical bore, 44, 111 a plane parallel to the bore in the bushing member. 7

ferred construction as herein shown, the

inking drum 25 is rcvolubly mounted upon a stationary shaft, 45, and is operated by a gear, d6, meshing with the gear 19 of the main shaft 17, said gear l-(i'being carried upon a collar, 47, revolubly mounted upon the shaft and carrying the inking drum.

To effect the delicate and convenient ad-, justment of the stationary shaft of the revoluble inking drum, a bushing member siin ilar to that before described withreference tothe eccentric mounting of the main printing-media shaft 17 is provided. Said turnable eccentric bushing for the hiking drum shaft has a body-disc, 48, the'inner face. of which bears against the outer face of the top extension 43 of the frame-block 39, and a tubular cylindrical extension, 49 projects from said inner face of said disc-body and is turnably mounten in the cylindrical bore 44; of the frame 43, which bore constitutes a corresponding cylindrical seat for said extension. 7 The extension 49 has its cylindrical circumference eccentric to, the center of the bushing body-disc l8, andv aoyliudrical bore, 50, is provided through said l)odydisc and its eccentric extension -19, whichbore extends longitudinally on the plane of the center of the bodydisc 48 and is eccentric to the center or axis of said cylindrical extension in it? turnable move ment. The stationary inking-drum shaft 45 passes through the bore 50 of the eccentric bushing, and is secured'therein by means of a set-screw, 51, passing through the bushing body-disc 48 to contact with'the shaft, or by any other suitable securing means The adjustment of the bushing for theinking-drum shaft is controlled by a set-screw, 52, passing laterally through the frame 43 to engagement with the eccentric bushingextension wl 'ch is turnable in its seat in the frame-bore 44-. Thus, by releasing the set-screw 52 the eccentric bushing may be turnably adjusted in a delicate desired movement to vary the plane of the shaft a5 carrying the inking drum 25, for the purpose before stated, after which the setscrew may be operated to secure and clamp the bushing in adjusted position. v

It will be understood that the improved &

eccentric bushing for the shaft of the ink ing drum or roller, as comprised in my present invention and hereinbefore described, is equally adaptable to conditions in which the inking-drum shaft is revolubly mounted and carries the inking drum in its revoluble movement, the shaft being not stationary but mounted and secured to revolve within the eccentric bearing-bushing in like manner to the mounting of the printingmedia shaft as herein set forth, or in conditions in which the inking drum operates merely as an idler upon a stationary shaft carried by the eccentric adjustable bushing.

The operation and advantages of my improvements will be readily understood by those skilled in the art to which my invention appertains. The mechanism is charac terized by simplicity in construction, and therefore economy in manufacture, and en ables very delicate adjustment for conditions of perfect efficiency, and with maxi mum certainty and convenience, to control the operative relationship between the printing media and the platen for perfect printing impression, and between the inking drum and printing media for perfect conditions of ink supply.

I do not desire to be understood as limiting myself to the detail features of construction and arrangement as herein shown and described, as it is manifest that variations and modifications therein may be resorted to, in the adaptation of my invention to varying conditions of use, without departing from the spirit and scope of the invention and improvements. I therefore reserve the right to all such variations and modifications as properly fall within the scope of my invention and the terms of the following claims.
